How to remove widget icons

What is the easiest way to remove the icons from the top of an individual widget? I have one widget in the latest viewer version (3.1) that I have added buttons to at the bottom of the widget to change the state of the widget. The same function that the icons at the top of the widget do.

I am not a trained developer so I'm trying to hack this together. Do I need a separate widget template or is there something I can toggle in the code to achieve this? Any help would be greatly appreciated.

Thanks!
